The construction of white-light-emitting anisotropic hydrogel - ScienceDirect

[Michael Hayes]

Highlights

•

Anisotropic fluorescent hydrogel is prepared via alignment of Fe/Al2O3 platelets.

•

The orientation-dependent shading effect endows anisotropic fluorescent properties.

•

White-light-emitting is achieved through adjusting the ratio of the two fluorescent emitters.

MH] This method requires a magnetic field for orientation of the particals, yet the orientation is fixed by hydrogel, and no further magnetic field is required. Designing a floating version of this fluorescent hydrogel may open the door for mCDR scale use. Layering of different hydrogels to create different qualities is likely possible. The floating hydrogel will be a barrier between the air/water interface, thus improving water pH as the air and water no longer can reach ionic equilibrium, and the 24 hr light likely will help subsurface microbes, thus reducing pCO2.

Moreover, such a vast scale deployment of an advanced multiplexed hydrogel in the mid Pacific, S equatorial ocean, may help regulate the ENSO due to the massive amount of water cooling that might be expected from the gel absorbing the solar energy at the surface as opposed to the solar radiation heating deeper into the upper water column. If so, the combined mCDR values and thermal reduction in subsurface waters, while in appropriate waters and at appropriate times, would seem to promise a tunable ENSO related GE method that can be adjusted seasonally.

Giving the floating hydrogel pastures floating borders is likely needed due to the frail nature of any hydrogel. Marine-grade reactor-based agricultural grow and processing tanks could act as effective borders. If so, the overall combined operation may realized a rather strong mCDR potential.
